From: Russ Gorby <redacted> Drivers are supposed to use the dev_* versions of the kfree_skb interfaces. In a couple of cases we were called with IRQs disabled as well which kfree_skb() does not expect. Replaced kfree_skb calls w/ dev_kfree_skb and dev_kfree_skb_any Signed-off-by: Russ Gorby <redacted> Tested-by: Yin, Fengwei <redacted> Signed-off-by: Alan Cox <redacted> Cc: Grooming <stable@kernel.org> --- drivers/tty/n_gsm.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-)
